Once upon a time, most processors took several clocks to do a single, integer add.
Then they invented "pipelining" and the number of clocks per add became smaller and smaller, until we had a processor that could do more than one add per clock. At the same time, floating point units are getting faster, although there are more likely improvements to simple operations like add or multiply that don't show up the same for cos() or sqrt(). ... and when we pick a golden reference machine, we're picking an architecture that defines the ratio between different types of ops. Are we going to base credits on one manufacturer's architecture (i.e. Core2) and then hope they don't "improve" that architecture, and that it stays available? I'm not saying I have a solution, but I certainly admire the problem. -- Lynn Martin wrote: > The Cobblestones_v02 MUST be calibrated on a "golden" reference piece of > hardware.
